> Self driving cars are already dependent on standard infrastructure markings such as lane lines, and whenever those markings are confusing or faded it has lead to fatal crashes, such as the fatal Tesla crash on 401.

A Tesla is not a self-driving car and they won't become one with that approach.

Waymo vehicles have virtual maps that include the lines (along with a LOT of other data) so they are not affected by fading lines as they always know where the lines are supposed to be.

Basically Waymo is building the infrastructure you all want, but in a virtual sense instead of the extremely expensive and impossible physical one.

> Waymo vehicles have virtual maps ...

You only need one reality <-> virtual desync to cause a crash.

[agildehaus]

Well no, it's not like the map is the only thing used.

How well does the Waymo approach hold up to a GPS failure?

[agildehaus]

GPS failure is the entire reason the LIDAR map exists. The map is used to give centimeter accurate location without any GPS availability.
